充分的部件采购规范对于硬件开发项目成功的重要性无论怎样强调都不为过。过于严格的规范可能和过于宽松的规范一样有害。例如，性能规范不仅必须确定所有组件要求，还必须包括足够的质量保证条款，以便验证合规性。应该理解的是，在几乎所有情况下，组件规范最终都将成为具有约束力的书面合同（PO）的一部分。本文件旨在描述规范，为流体成分规范的编制提供指导，并确定流体成分规范中通常引用的文件。

The importance of adequate component procurement specifications to the success of a hardware development program cannot be overemphasized. Specifications which are too stringent can be as detrimental as specifications which are too lax. Performance specifications, for instance, must not only identify all the component requirements, but they must also include sufficient quality assurance provisions so that compliance can be verified. It should be understood that in almost every case specifications for components will ultimately become part of a BINDING, WRITTEN CONTRACT (PO). The purpose of this document is to describe specifications, provide guidance for the preparation of fluid component specifications, and identify documents commonly referenced in fluid component specifications.
